If your Samsung Galaxy S4 on Verizon has been randomly rebooting, you might want to check for a system update. No, it's not getting Lollipop, but Verizon says that this update does fix "the intermittent power cycle issue." Translation: before this update the phone crashed. Now it will not crash. We hope. The only other change for software version KOT49H.I545VRUFNK1 (PDF link) is a VPN connectivity fix.

Verizon's S4 has gotten a few of these small updates, so you should know how it goes by now: any modification to the system or the recovery will cause a flash error, and if you have root before the update it's possible you might lose it afterward.

We've been hearing from a lot of companies hyping up their plans for Android 5.0 updates - at least one of them seems ready to start issuing it soon. But what of Samsung, the undisputed king of Android sales figures and, not least, one of the more (ahem) robust suppliers of add-on software and interfaces? Apparently the company is working swiftly on a Lollipop update. The folks at SamMobile, as is their wont, have already managed to snag what looks like an early build of Android 5.0 for the Galaxy S4.

Verizon Wireless has rolled out the details for its next over-the-air update for the Galaxy S4. These devices aren't getting hit by a new version of Android, but owners will see various connectivity improvements that they may or may not notice. The default messaging app should be more reliable, Bluetooth connections should be stronger, and voicemail should arrive more consistently.

The update slips in the second version of Knox and replaces ISIS Wallet with its new name, Softcard.

Samsung releases so many phones in so many variants that even professional gadget bloggers get turned around on occasion. But the folks on the CyanogenMod team are doing their best, bless 'em, and today's fruit of their labor is ROM support for an extra variant of the Galaxy S5 and Galaxy S4. The most pertinent one for American readers is probably the G900-T, the Galaxy S5 model sold by T-Mobile as their branded version.

An over-the-air software update is set to hit AT&T's version of the Galaxy S4. The change log for this one isn't particularly long, but it will bump users up to baseband number KOTH49H.1337UCUFNB1. There's a certain satisfaction that comes from having the freshest set of software available on a device, and that feeling is what the bulk of owners will notice about this release.

As for what's actually new, AT&T says this update will provide better connectivity when making calls and text messaging.

Update: T-Mobile has updated the support page with a clarification on those Wi-Fi calling enhancements. The phone now has support for Gogo inflight texting, a feature the company announced as part of Un-Carrier 7.0.

WatchON is a Samsung-exclusive offering that serves as a universal remote and TV guide all bundled up into one place. When the Galaxy S5 launched earlier this year, the Korean conglomerate released an updated version of WatchON for its new flagship device and introduced the app to the Play Store for the first time. Yet despite this Google Play presence, the updated version remained exclusively available to the Galaxy S5, and Samsung's other handsets were left with an older version of the pre-installed software.

Sprint has announced that an over-the-air software update is due out for its version of the Galaxy S4 going by the name of version number L720VPUFNG2. The changelog for this one is pretty minor, so there's little reason to start abusing that update button. Galaxy S4 owners should be on the lookout for an HD Voice icon (which they might be able to notice), and a number of security patches (which they won't).

Google officially pulled the HTC One M7, Galaxy S4, Xperia Z Ultra, and LG G Pad 8.3 Google Play Edition devices from the Play Store not too long ago. Since then we've seen a couple of them pop up on sale across various distributors. When an eBay seller offered the Galaxy S4 for $499 ($150 off) last month, we considered that a deal. Before that, Expansys USA offered the Z Ultra for the low price of $349, $100 less than what Google last asked for it.
